Y My invention. relatestowater purifiers, particularly .to those used withA steam boilers y andthe.lilre,wherein there is provided a cas-'- ing. through which. `thefw-ater to be purified is adaptedtoflow and wherein'it is subjected tothe purifying action of particlesdetachedfromv abrasive balls.

andtoebethereby abraded, the niaterialsvof' which'. the-balls, and preferably also of 'the the impurities of the water. Such a water puritieris disclvcsedin. the McGray and Hatch Patent No. 1,099,459, dated-June 9,1914.

It was also known, at an earlier date, to force the water lto be purified through a race-way containing' ballsl carrying materials adapted to correct the impurities of the water, Atheballs being forcibly propelled by the water, as disclosedi in` the SiinmonsPatent No. 867,430, dated October 1, 1907. A

In neither patentedy waterpurifier, however, is every part ofthe water brought into direct andY intimate contact withall the balls of a race-way or with any substantial proportion of them. 'In the patent of earlier Y date, the Vballs are spaced apart in the raceway at distances relatively great proportionately to their diameters and only the fore and aft parts of the column of-water in the space'between anytwofballs actually contact Vwith the balls. In. the patent of later date the water is merely introduced into a rotating cylinder in which the balls are contained and roll, and flows down past the balls,but v every part ofthe. water is not brought into. directv and intimate Contact with an "entire,

series of' balls.

The principal obiects of, the present invenf tion'aretto provide awater puri'er oftheI character describedbut the, construction of which is so. substantiallymodified as to in-V sure the` circulation of water'to be purifiedA through -one or more ball race-waysin suchmanner as toefl'ect `direct andintimate contact4 of the. water with most .or all of' the series of balls containedin, a race-way. thereby effecting the distributienet'abradedfparticles with substantialY uniformity throughf out the water flowing through the feed pipe; also to ,provide improved means for carrying;

the race-way or race-ways and for directing `the water into the Vsarneand water away therefrom. y f

My invention comprises a construction conveying the rIhese balls are lcaused` tormove in contactwith drums or the like 20,1-926f. snaai nieassen wherein the above objects" lare l attained" and which also embodiesotlier structural' fea` turesproniotive.ofefficiency.

A preferred embodiment ofthe invention Fig'. l is a longitudinal' elevation. princi- 'the feed pipe of steam@ boiler,)sprovidedv with an inlet 6 and an outlet' cie A partition d divides the casingl into a relatively large' inlet chamber e anda relatively small outlet' chamber .Extending through both charnbers ofthe casing is av shaft g that isadaptedto be rota't'edy in suitable stuffing bo'xesh in the outer' wall" of the casing and' is driven by any suitable means. Y Y v y 'f fr 'cylinder i, whose endhubsare keyed togsnaft g, extends linto both` chambers e and f and/substantially throughout' the; length ofthe' casing, the body of the khub turning in a watertight ring .j inpartition all' T/Vithin chamber e and surroundingcylinder is a` circular ball container, the same comprising va hub .7c secured'` vto the cylinder, oppositely positioned webs .or neclrsm 'and' n projecting from the hub, and anl annular` ball race-way o carried r`by such webs ,or

necks. Preferably, aseries of such ball-con?V BCV itainers are provided,` four*being shown in'A A the drawings. v Each ball race-way o is provided with da.Y

ter-iol1 of,l chamber` e. ball containeris' provided withal wateroutlet channel-mth@ also egt-ends,- through hub"v /clandcommunicates w'i'thtle ball race-way o andan orifice' s in cylinder. Yiate'r"Vv outletf p and water outlet 1" are preferably'floc'ated', opposite, or nearlyy opposite', one another; The water inlets ofadjacentlball containers are preferably in staggered" relationship', asarethe water outlets Vof1 adjacent bail-'conf-f` tainers.. j

In chamber toaillowf for" outflow of water.v

' Within" each' ballrac'e-way' ois series cof` ballsf. rl'he ball race-way 0 may be -ini-4 tially of a cross-section but little exceeding the diameter of the ball, andthe frictional wearing face of the race-way should be curved, in `cross section,`on a radius nearly 9o waterinlet p communieati ngj` with the in The n'eck m off eachi loo f," cylinder" ist` at", 25.1

or quite corresponding to the radius of a ball. There is thus provided, When the purifier is first installed, a substantial area of frictional contact between the balls and the Wall of the race-Way', thus insuring an adequate abrasive action between them. As the balls Wear away, so does the Wall of the race- Way and a channel is 'formed in the latter, the contour o f which continuously adapts itself to thechangingcontour of the spherical f'ace of the lball arising from its continuous 'shrinkage in diameter.

The balls and the Walls ofthe race-way may be of' any suitable compositions. Thus the race-way may be composed of gra-phitic cast iron with or Without othermetals mixed therewith. The balls may be composed of an alloy of graphitic cast iron with other metals; or they may be composedV of pulver ized graphite and one or more other metals such as iron, aluminumand zinc, the inaterials all being bound together by a binder such as sulphur'. Both the balls and the race-Way may be of the same material, in

which case graphitic cast iron would be a preferable dominant constituent. Suitable abradable materials for Water-purifying purposes arelnoivn in the art, and the present invention contemplates the use of race-Ways and balls of any compositions that may be found eflicient.

In operation the boiler feed Water to be purified enters the chamber e through the linlet b and flows from the chamber e through the inlet j) of one of the ball race-Ways. Thence the'ivater is compelled to make approximately a half circuit of the race-Way 0, and is brought into direct contact with the entire series of balls before it can escape through the outlets r and s into the interior of the cylinder z'. As the Water flows through the ball racewvays, the ball containers are continuously rotating and the balls move along the Walls of the race-Ways and particles areabraded both from the balls and the Walls of the race-Ways. The particles thus freed have a purifying action on the Water. Y

The purified Water that enters the interior of the cylinder i escapes therefrom.through the orifices t into chamber f and thence through outlet c.

Having novv described my invention, what I claim and desire to protect by Letters Patent is:

1. A vvater purifier comprising a casing provided with a Water inlet and a Water out let, a rotatable circular enclosed ball race- Way within the casing, and a series of abradable balls rollable Within the race-Way, the race-Way being provided With a Water-admission openingl connnunicating With said inlet and a Water-discharge opening communicating with said outlet, said openings being so spaced apart as to compel a flow of Water in a circumferential direction for a Substantial ,distance through that part of the race-Way in which the abradable balls roll.

2. A Water purifier comprising a casing provided With a Water inlet and a Wateroutlet, a series of circular enclosed ball race- Ways arranged side by side Within the casing and rotatable together about a common axis, and a series of' abradable balls rollable within each race-way, the Water admission openings of adjacent race-ways being located on different radii of the common axis of rotation and the Water discharge openings of adjacent race-Ways also being` located on different radii of the common axis of ro-V tation.

3. A Water purifier comprising a rotatable cylind-r provided With a Water outlet, a ball race-Way surrounding` the cylinder and rotatable therewith and adapted to contain a series of abradable balls, the race-Way having a Water admission opening, the race- Way also having a Water discharge opening` communicating With the interior of the cylinder. l

t. A. water purifier comprising a casing divided into a Water inlet chamberl and la Water outlet chamber, va rotatable cylinder extending into both chambers and provided with a Water outlet communicating With the Water outlet chamber, a ball race-Way adapted to contain a series of abradable balls and surrounding the cylinder and rotating therewith and having a Water admission opening ccn'nnunicating with the Water inlet chainber and a Waterdischarge opening com-,`

municating With` the interior of' the cylinder.

5. A Water purifier comprising a rotatable cylinder provided with a Water outlet and a Water inlet opening, a ball container surrounding and secured to the cylinder, and comprising a hub, an enclosed ball race-Way and necks connecting the hub and the race- Way, the race-Way having a Water' admission opening, one of said necks having a channel formenL therein affording an outlet for Water from the race-Way to the Water inlet opening inV the cylinder.

In testimony of which invention, l have hereunto set my hand at Chester, Pa., on this 2nd day of February, 1926.
